When thinking about fluid within the body we are essentially thinking about water. Tight regulation of the balance between water intake and output, and its distribution, is vital to the optimal function of every organ system within the body. In a wide variety of illnesses and during surgery, disturbances to this fine balance occur which must be identified and corrected to prevent deterioration,...

CM-A Body Fluids

C M P0 4 The arrowed objects are tyrosine crystals. Tyrosine crystals are rare and their presence in urine is always abnormal. They form clusters of silky needle-like structures that are colorless, or black on focusing. Tyrosine crystals are found in acid urine, increase after refrigeration, and are insoluble in alcohol or ether. They are soluble in dilute hydrochloric acid, alkali and relative...

Acetylsulfisoxazole in Body Fluids

We describe a simple, rapid chromatographic method for separating and quantitatively determining sulfisoxazole and its N4-acetyl metabolite in plasma and urine. A 100-zL sample of plasma or urine is combined with 200 tL of a solution containing 12 mg/L of the internal standard, Nt acetylsulfamethoxazole, in absolute methanol and centrifuged to obtain a clear supernatant solution. This solution ...
